After they made press last August claiming a breakthrough, I checked up on them every couple of weeks. It has been crickets and had been assuming this was another false hope. Perhaps it still is, but happy to have hope still alive.

Excuse me, I guess I wasn't right either. This is Li-Metal which is apparently different than solid state lithium... I guess I need to go read some.

I did find this:

I contacted SES (Solid Energy Systems) yesterday, because the specs of the Hermes battery cell had a typo, I used the opportunity to ask them when do they expect to have it commercially available. The response I got was that it will be available mid next year in commercial drones.

They seem to be in exactly the same place they claimed to be about two years ago.

The company is currently testing its batteries for drones and expects to begin selling them later this year, followed by batteries for wearables in 2019 and for electric vehicles after 2021.

Also:

At $500 per kilowatt-hour, SolidEnergy’s battery is currently much pricier than conventional lithium-ion batteries, which now sell for about $200. But Hu expects costs to go down with large-scale manufacturing and is talking with major battery makers.

Doing some back of envelope guesses and they are claiming to have a energy density equivalent to TNT.How stable is this stuff If it decides to spontaneously disassemble, i mean current batteries are bad enough.

If you look back to two years ago in their original press release and news stories (too lazy to search right now), pretty much the same as that too. Actually, I think at that point they were projecting cars in two years at that point, now they say three.

Last year I was excited to see they weren’t dead— this year I’m pretty much convinced they are.
